I'm sorry, but this will never see adoption wide enough to be useful.
I can't imagine paying 800 and still having to carry a "backup" phone for payments, public transit and such.
At that cost I'd think more about seeking out a second hand phone that's survived and has good parts availability/repairability to keep it going. It would seem with both you're in the situation where google doesn't about you but at least the phone would be semi-smart enough to do some tasks and less drain on the wallet.
